Vehicle Interior Noise Prediction Using Tire Characteristics and Vehicle Transmissibility

Vehicle interior noise is generated not only by excitation from road asperity but by tire tread pattern irregularity, and is considered to be transmitted through two noise paths, structure-borne and air-borne. Therefore, in the development of vehicles and tires, it is important to know the transmission mechanism through each path and to control noise in the frequency domain.

This paper describes a method to predict vehicle interior noise using measured vehicle transmissibility and given tire characteristics.
